The evaluation of current level of neuropsychological functioning is handicapped by the lack of validated actuarial methods for estimating premorbid intellectual functioning. The present study cross-validated and attempted to improve the one existing method of using demographic variables in a systematic way to predict WAIS Full Scale IQ (Wilson et al., 1978). A sample of 491 neurologically normal subjects was used. The results generally supported the IQ prediction equation, but did reveal systematic differences in accuracy of prediction and direction of prediction error for IQs in the high and low ranges. Also, a simpler IQ prediction formula that uses only years of education was developed and compared with the 5-variable Wilson et al. formula.
由于缺乏用于估计病前智力功能的有效精算方法,当前神经心理功能水平的评估受到了阻碍。本研究对现有的一种系统使用人口统计学变量来预测韦氏成人智力量表全量表智商的方法(Wilson等人,1978年)进行了交叉验证,并试图对其加以改进。研究使用了491名神经功能正常的受试者作为样本。结果总体上支持智商预测方程,但确实揭示了高智商和低智商范围在预测准确性和预测误差方向上的系统差异。此外,还开发了一个仅使用受教育年限的更简单的智商预测公式,并将其与包含五个变量的Wilson等人的公式进行了比较。
